    This just in, scientists unveil “a loop of wire”

    I keed, I keed. Glad to see materials science improving technologies we have for new applications.

    Do you need to hazardously close to a tower for good stability? Fascinating for the future of wireless power!

      It’s almost certainly going to be milliamps or microamps unless you’re inches from something. This isn’t for cellphones and the like but for remote sensors and the like. I also bet they’ll at least have to have a capacitor to store up extra charge for chirping back only sometimes.

    Uhm, how is this fundamentally different from a crystal radio? I’ve built this exact concept from a science kit, and this is a concept that’s been proven for decades.
